Abstract

1421018 Polymers containing N,N-disubstituted acrylamide units BAYER AG 11 April 1973 [11 April 1972 1 Feb 1973] 17301/73 Heading C3P Polymers containing N,N-disubstituted acrylamide units are prepared by reacting a poly- (acrylic acid-C 1-4 alkyl ester) with an amine of formula in which R 1 and R 2 are each alkyl or cycloalkyl radicals having up to 18 carbon atoms, n and m are each numbers from 1-11 and X is -CH 2 -, -O-, -S- or in an aprotic amide group-containing organic solvent at 100-250‹ C. under a pressure of 0-100 atmospheres. The products contain acrylic acid and ester groups as well as amide groups, and may contain two different types of amide units in cases where the secondary amine reacts with the solvent to release a different amide. Suitable solvents include dimethyl formamide and N-methyl pyrrollidone, others being listed. Numerous different amines are used in the examples to react with poly- (methyl acrylate) or poly-(butyl acrylate).
